POLYPHENYLACETYLENE POLYMER, ITS MANUFACTURING METHOD, AND ELECTROCONDUCTIVE MATERIAL AND STIMULUS-RESPONDING MATERIAL CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyphenylacetylene polymer which is excellent in electroconductive properties and electromagnetic shielding properties, isomerizes structurally by a solvent treatment or a pressurization treatment to cause changes in its color, and therefore is useful as an electroconductive material, an electroluminescent material or a pressure-sensitive material such as a pressure sensor. SOLUTION: The polymer is represented by the general formula (wherein R is a hydrocarbon group or a heteroatom-containing substituting group; Z1, Z2, Z3, Z4, Z5, Z6, Z7and Z8are each independently hydrogen, a hydrocarbon group or a heteroatom-containing substituting group; and n is an integer of at least 10).
